[PATCH 3.11 061/233] spi/bcm63xx: don't substract prepend length from total length

[Luis Henriques]

3.11.10.4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jonas Gorski <jogo at openwrt.org>

commit 86b3bde003e6bf60ccb9c09b4115b8a2f533974c upstream.

The spi command must include the full message length including any
prepended writes, else transfers larger than 256 bytes will be
incomplete.
